I've done KOA Kissimmee, ususally for 2 nights before or after, but did it once for 6 nights. It's a KOA, meaning you're neighbors are close; but it's actually pretty nice for one, and not as giant as some of them are, less than a 100 total spaces. They have a nice heated pool area in the back; pre-covid they kept it open 23 hours a day, they're currently closing it at 9. Believe it's running between 75-90 depending on the site, the pull through full patio sites are actually pretty nice. One thing I did like about it over the fort is all the nearby dining options.
